Tube Flattening Tests

Tube Flattening testing reveals the compression strength of the tested metallic tube. A pass/fail test, tube flattening is used to determine whether or not the tube will rupture upon flattening.

To perform the test, a section of tubing is flattened under a specific load using the tensile machine. Next a visual inspection is performed, observing the damage evident in the surface of the tube. If there is no visible damage to the surface of the tube, the specimen passes. If the tube shows damage, such as cracking or orange-pealing the specimen fails the test.
